Roger, I sent a reply but it hasn't shown up so here's take 2... In this case, what I'm trying to determine is the minimum distance I can measure to a fault.. I used 4.8mm to simplify this

Roger, Mainly I'm trying to determine the minimum distance to a fault that I can measure. I understand that the 4.8mm number is dependent on the VF, I was only trying to keep things simple for this

You need to be calibrated over the frequency range that you select. However there is calibration interpolation used on some NanoVNA's, like the -H and -H4, so you can arrow the frequency range if you

Yes, that's what I do, not a problem...

Make sure you enter the VF as a percentage not a decimal value. EXAMPLE 60 not .60 *Clyde K. Spencer* wrote:

I have a couple questions regarding using the Transform function to measure length of a cable. How does calibration affect the Thansform measurement? If I set the stimulus start and stop to 50KHz

That will be a very interesting comparison test! I hope you publish all the details and measurements. (Great choices of antennas, too. My full-wave horizontal loop is terrific.) -- Doug, K8RFT

Nuno, I was pretty happy with my NanoVNA-F V2 until it randomly died on me. It lasted nearly 2 years though and had zero issues with it before it died. I took a gamble and purchased the SV4401A

I forgot to add this link https://nanorfe.com/nanovna-v2.html

The only potential downside to the V2 is that they are more sensitive to ESD, because they have a monolithic RF switch at the input.

Likewise. I would recommend V2 Plus4 or V2 Plus4 PRO from an official store. There are several other version but I like V2 Plus4. Today perhaps PRO version. Battery lasts a long time and results are

i have finaly got my pc to tato the vna,ready to load fw,can anyone tell me what FW has the biggest fonts with the most save slots,thanks.

Is not easy as you said. It needs to be new design and higher speed components. See link: https://nuclearrambo.com/wordpress/reveiwing-the-new-nanovna-v2-saa-2-part-1/ FC

Hi,i tried using teraterm on my vna,it connected ok using com 19,i ran learconfig 1234,now it wont connect to my pc,terraterm only sees com 1 not 10,the stm32 bootloader tab in device manager says

Connect it via USB and open the serial port in a terminal program, bitrate etc. is not relevant. Type e.g. "help" to see the available commands.

Do i need to connect it to my pc,if so how,i see no guides for doing it.thanks+73

I have two other nanoVNAs but I find myself reaching for the SAA-2N most often. The calibration kit and cables provided are of good quality and have held up (so far). For higher frequencies I have a

many of the models can be easy improved (lower noise above 2 ghz with just some decoupling caps added) .. i bet yours is similar :-) dg9bfc sigi ps welcome in the group of fancy smith diagramms ,

I have the H H4 SAA2N and the F models and use them in different applications. If you intend to use it outdoors I strongly recommend the F model with the pushbuttons. It has the brightest display
